Definitions
- the invention relates to a fan assembly, and relates to a method for Production of such.
- the vibrations generated by a fan are disturbing felt. Such vibrations are caused by the normal drive of the Fan wheel, as well as load and speed changes. The vibrations will be from the fan to the entire device in which the fan is located transfer.
- this object is achieved by a fan assembly according to Through the membrane is a good decoupling by the Fan generated vibrations from the mounting frame, and when the Fan assembly is closed on its pressure side, is a backflow of air possible from the pressure side to the suction side.
- FIG. 1 shows a plan view of a first exemplary embodiment of a fan arrangement 40 according to the invention with a fan 10, as seen from the direction I of FIG. 2.
- FIG. 2 shows a side view of the fan arrangement 40, seen in section along the line II-II of FIG. 1.
- the fan 10 has an electric motor 12 with a stator assembly 14 and a Rotor 16, also fan blades 18, webs 28, a motor bracket 29 (see Fig. 3) and a fan housing 30 with a lateral projection 31 on.
- the axis of rotation of the Fan is designated 50.
- the fan assembly 40 has a membrane 32 with a plurality of openings 33, and a fixing frame 34 having a projection 35, a Mounting frame holder 36 and a mounting opening 38th
- the stator 14 is connected via the webs 28 with the fan housing 30 and drives the rotor 16 at.
- the fan blades 18 are set in motion, and it an air flow flows through the region 20 between the fan housing 30 and the Stator 14.
- Shown is an axial fan 12, but the invention is in the same Way e.g. for diagonal fans.
- the fan housing 30 is over the circumferential annular membrane 32 with the Attachment frame 34 is connected, which in this embodiment two Mounting frame holder 36 has.
- Mounting holes 38 in the Mounting frame holders 36 serve for fastening the mounting frame 34 and thus also the fan 10, for example by means (not shown) screws.
- the membrane 32 thus connects the fan 10 to the mounting frame 34.
- Sie encloses - for the purpose of secure connection - both a projection 31 am Fan housing 30 and a projection 35 on the mounting frame 34th Die Projections 31, 35 may also be dovetail-shaped.
- the projections 31, 35 extend around the whole Circumference of the fan around, so 360 °.
- the fan housing 30 and the Mounting frame 34 are thus both on the side of the fan housing as also on the side of the mounting frame over the entire or in essentially elastically yielding over the entire circumference connected.
- the fan housing 30 and the mounting frame 34 and in this Embodiment with these integrally formed projections 31, 35 are preferably made of plastic or metal, and the membrane 32 is made preferably of an elastomer.
- the fan housing 30 and thus also the fan 10 are through the membrane 32nd both in the axial and in the radial direction in the desired position relative to held the mounting frame 34 and thus form the fan assembly 40th
- connection is not rigid, but elastic and capable of oscillating. While rigid connections vibrations of the fan 10 largely unattenuated on the Transfer frame, the membrane 32 is made of an elastomer to a desired greater damping in the transmission of vibrations of the fan 10 on the mounting frame 34th
- a membrane 32 is capable of vibration because it is relatively thin. As can be seen in FIG. 2, has the membrane at the edge regions 32 ', where they on the fan housing 30th and the mounting frame 34, one for a secure connection suitable thickness. In the middle of 32 "she is thin, so that the fan 10 itself can move relative to the mounting frame 34.
- the attenuation through the membrane 32 is dependent on the to be transmitted Frequency and of the membrane properties, ie in particular of material and Shape of the membrane.
- Each fan 10 generates vibrations in characteristic for him Frequency ranges.
- a suitable one is preferable Plastic, in particular an elastomer used in which the hardness can be varied can.
- a measure of the hardness is the so-called Shore hardness. It is also one Combination of different materials possible.
- the basic form of Membrane adapted openings in the membrane are formed, and the thickness the membrane is varied.
- openings in the membrane are formed, and the thickness the membrane is varied.
- FIG. 3 shows a partially sectioned side view of a second exemplary embodiment of a fan arrangement 40 according to the invention, in a section corresponding to FIG. 1.
- the membrane 32 is in this embodiment in cross-section U-shaped trained, and the fan can therefore vibrations with larger Perform vibration amplitudes. This is especially for damping low-frequency oscillations advantageous.
- the membrane 32 has at the bulge 32 '' 'one or more openings 33. Due to the lack of material and thus the mass at this point is the Vibration property of the membrane 32 influenced.
- the opening 33 has the advantage that in applications in which the Pressure side is closed - for example, when a driver is on the Vehicle seat sets and all outlet openings hidden - a so-called ventilation short circuit is avoided, since the air through the opening 33 on the Can flow back suction side. This allows the fan 10 continues in a preferred workspace work.
- the exact configuration of the openings 33 is preferably chosen in consideration of this aspect.
- FIG. 4 shows a partially sectioned side view of a third exemplary embodiment of a fan arrangement 40 according to the invention, in a section corresponding to FIG. 1.
- the membrane 32 of the fan assembly 40 is in this embodiment Wavy or approximately sinusoidal and has several Bulges 32 '' '. Due to the greater length of the membrane 32, the fan 10 in perform stronger movements both axially and radially.
- FIG. 5 shows a partially sectioned side view of a fourth exemplary embodiment of a fan arrangement 40 according to the invention, in a section corresponding to FIG. 1.
- a membrane 32 is here materially bonded to the fan housing 30 and the Attachment frame 34 connected. So there are no projections 31, 35 present, with which the membrane 32 is positively connected.
- the material of the membrane 32 must be suitable, e.g. with the Surface of the material of the fan housing 30 and the mounting frame 34th makes a chemical connection.
- the edge regions 32 'of the membrane 32 are widened to a larger surface area for to get the connection.
- FIG. 6 shows a plan view of a fifth exemplary embodiment of a fan arrangement 40 according to the invention.
- the fan housing 30 and the mounting frame 34 are above a membrane 32nd connected, which is provided over the entire circumference with oblong holes 33 ', which round or rounded ends 37 'have.
- a membrane 32 is a U or Wavy membrane used, so are the holes 33 'preferably on an axially highest or lowest point, cf. Fig. 3.
- the projections 31 'and 35' are in this embodiment in regular Interrupted intervals. If the positive connection to the projections is not sufficient for a secure hold of the membrane 32, this is preferred at least in the places without projections 31 ', 35' additionally cohesively connected.
- FIG. 7 shows a plan view of a sixth exemplary embodiment of a fan arrangement 40 according to the invention.
- the fan housing 30 and the mounting frame 34 are above a membrane 32nd connected, which is provided with angular slots 33 ", which is substantially rectangular ends 37 "have.
- the recesses 33 in addition to round, oval, quadrangular shapes, triangular, polygonal, have square or other shapes. By choosing the shape of the Recess 33 can for the respective engine type a good vibration behavior of Membrane 32 can be achieved.
- the projections 31 on the fan housing 30 and the projections 35 on Mounting frame 34 may be formed differently, the shape of the Projections can be varied, and the possible interruption of the projections 31 and 35 around the circumference can be varied.
- the attachment of the mounting frame 34 to a component to be cooled also be elastic, in addition to a vibration transmission minimize.
- FIG. 8 schematically shows an upper injection mold half 60 and a lower injection mold half 62
- FIG. 9 schematically shows a holding device 70, an upper mold part 72 and a lower mold part 74.
- the upper mold parts 60 and 72 each have channels 80 and 82, respectively through which the material to be processed is supplied.
- the fan housing 30 possibly with the webs 28 and the Motor holding cup 29
- the mounting frame 34 for example in Injection molding process, over the channels 80 molded from a hard plastic and held in the correct relative position to each other, cf. Fig. 8.
